Gouach

The repairable battery

We are building a battery which is feature-packed, easy to use and fully repairable.

We love e-bikes! But as they become increasingly popular, we start to see more and more people frustrated with their batteries.

Existing batteries are too impractical and dangerous to repair, and often end-up being discarded for only minor defects.

This results in a lot of ecological and economical waste.

Gouach set out to build the first sustainable and fully repairable electric battery.

Our team invented an easy-to-use battery that is as reliable and powerful as market leaders, but is also eco-friendly.

The Gouach battery is packed with features, fully customizable, and comes with an easy-to-use API, documentation, and friendly community.

Protecting our environment just got easier!

Developer superpowers!

We believe that a battery should be feature-packed, easy to work with and designed for your needs.

Fully customizable.

We offer custom form-factors to fit in any product.
